### Performance Improvements
* Fixed an iterator performance regression for delete range users when scanning through a consecutive sequence of range tombstones (#10877).
### Bug Fixes
* Fix FIFO compaction causing corruption of overlapping seqnos in L0 files due to ingesting files of overlapping seqnos with memtable's under `CompactionOptionsFIFO::allow_compaction=true` or `CompactionOptionsFIFO::age_for_warm>0` or `CompactRange()/CompactFiles()` is used. Before the fix, `force_consistency_checks=true` may catch the corruption before it's exposed to readers, in which case writes returning `Status::Corruption` would be expected.
## 7.8.0 (10/22/2022)
### New Features
* `DeleteRange()` now supports user-defined timestamp.

* Fixed a bug where RocksDB could be doing compaction endlessly when allow_ingest_behind is true and the bottommost level is not filled (#10767).
* Fixed a memory safety bug in experimental HyperClockCache (#10768)
* Fixed some cases where `ldb update_manifest` and `ldb unsafe_remove_sst_file` are not usable because they were requiring the DB files to match the existing manifest state (before updating the manifest to match a desired state).
* Fix FIFO compaction causing corruption of overlapping seqnos in L0 files due to ingesting files of overlapping seqnos with memtable's under `CompactionOptionsFIFO::allow_compaction=true` or `CompactionOptionsFIFO::age_for_warm>0` or `CompactRange()/CompactFiles()` is used. Before the fix, `force_consistency_checks=true` may catch the corruption before it's exposed to readers, in which case writes returning `Status::Corruption` would be expected.
### Performance Improvements
* Try to align the compaction output file boundaries to the next level ones, which can reduce more than 10% compaction load for the default level compaction. The feature is enabled by default, to disable, set `AdvancedColumnFamilyOptions.level_compaction_dynamic_file_size` to false. As a side effect, it can create SSTs larger than the target_file_size (capped at 2x target_file_size) or smaller files.
